摘　　要：人口空间密度数据对于各国家和地区制定发展规划和方针政策具有重要的参考意义,中国人口数据每十年普查一次,耗时耗力且缺乏空间信息。因此,本文通过建立行政区人口密度与不透水面密度之间的关系模型,并结合开源地图(OSM)数据,提出建立30 m像元尺度的人口密度空间分布方法。结果表明,北京市30 m像元最大人口可达36人,均值为12人,通过对比Worldpop人口密度数据,人口密度在30 m像元尺度上的空间细节信息较行政区尺度有明显的提升,该成果可用于快速获得城市人口空间分布数据,为城市管理和规划人员提供数据参考。Population spatial density data is of great reference significance for countries and regions to formulate development plans and policies.China′s population data census is conducted every ten years,which is time-consuming and lacks spatial information.Therefore,by establishing the relationship model between the population density of administrative region and the density of impervious water surface,and combining open street map(OSM)data,this paper proposed to establish the spatial distribution method of population density at the pixel scale of 30 m.The results showed that the Beijing 30 meters is 36 people,like yuan maximum population average of 12 people,through comparing Worldpop population density data,the population density in 30 meters space details like yuan scales has obvious improvement than administrative region scale,the results could be applied to quickly get the urban population spatial distribution data,provide data for urban management and planning personnel.
